Press the Green Flag and watch as a hinge rotates the beam back and forth. Use your mouse to make the beam point at the mouse and release to see it swing back and forth like a real hinge would swing. This is 100% Pen and why did I make it in pen? I thought that it would be more fun to make it in pen and more challenging. Encountering some problems I soon discovered what they were and was able to fix it so that people could use there mouse to control it with no problems at all. If there are any bugs, please report them to me so that I can show this project at its best and make sure everyone has the best experience possible Thanks, and enjoy the project now for me. If you enjoyed it then please like and favorite so that I can get more noticed. I would deeply appreciate it if you would. Try and get it at 0 degrees cuz it won't move if you do.
